A few sites I've stumbled across recently....

The Chinese might have some success with making cars in S. Africa - but the education systems and social norms further north require probably a generation of upgrades to develop the workforce into viable factory workers ... exports will predominate.

Ford had an assembly site in S. Africa which also made local models eg Sierra V8.

"...generation of upgrades to develop the workforce into viable factory workers..." is rather optimistic, we tried for a few hundred years with no success and since Mandela elected, SA has been going backwards.

.
Here's a thought to ponder/debate: perhaps there's a logical/economic reason why the Egyptians, Greeks, Romans and then Moslems captured sub-saharans and traded them as slaves.

Anyone able/willing to do a comparison of:

EM's http://www.esri.com/news/arcuser/0703/geoid1of3.html

and

http://moocs.southampton.ac.uk/oceans/2014/11/09/amphidromic-points-tidal-spiders-in-a-real-world/

Wondering if tides correlate with EM's highs.

Thanks for that link, I spent an interesting quarter hour looking at some familiar names. None of the schools being relevant as I'm the product of an underfunded state High School.

You're welcome :)

Until my parents moved to Scotland from NI, I was at a state Grammar School, as was my brother.

We visited local comp. Headmaster asked what my career choice was; I replied "Doctor/Surgeon". He told us to go private as Local Authority restricted pupils to two science subjects - thus APH/pre-Med, Biol, Chem & Physics not permitted.

To say we were rather shocked is an understatement. Family budget changed from two cars to one; one foreign 2 week holiday plus 2 or 3 UK short breaks per year to one foreign 2 week "trade"* holiday every 2 or 3 years; no Scouts, no....

.
* trade - related to business so partially tax-deductible, but parents in lots of visits and meetings - many boring hours waiting in car for parents return.

Thank you for your post at 10.07 a.m. today. Please don't worry about the delay in responding; I often make a comment then find I don't have time to interact again for several days.

I'm in no position to get involved in your dispute with Supertroll about the relative ease or difficulty in taking sediment samples for more recent periods. So I'll leave the pair of you to it.

Regarding your latest link (Antarcticglaciers.org "Explaining the science of Antarctic glaciology) I've had a look, but am still not convinced. Once you use different forms of proxies to cover different periods of your graph, then it seems to me that the graph as lost consistency. To offer a continuous temperature proxy, it seems to me you need to use the same proxy throughout the period of the graph for it to be meaningful. If you starting splicing different proxies onto graphs, because they give the results you want, then you're in difficult territory. And if the latest graph you offer still only takes us to 1950, then we're still almost 70 years out of date.

By the way, please can you explain this -

Your first link said this:

"What the authors found was very interesting. Using data from 642 sites across North America and Europe, the temperatures they found closely matched those expected from computer simulations. They found that throughout most of the Holocene period (the last ~11,000 years), the Earth was warming very slightly. Only in the last ~2000 years has the Earth been in a cooling period (which probably would have continued except that human emissions of greenhouse gases have now reversed the cooling)."

Your latest link says this:

"Although the Earth has not yet exceeded the temperatures of the Early Holocene (5000 to 11,000 years ago), global temperatures have risen from cooler than 95% of the Holocene at around 1900 to warmer than 72% of the Holocene in the last 100 years (Figure 5). This means that, in the last 100 years, the Earth’s temperature has reversed a long-term cooling trend that began around 5000 years ago to become near the warmest temperatures during the last 11,000 years."

So a study you link to using one set of proxies says that the earth has been warming gently for most of the last 11,000 years, cooling for the last 2,000, but has started warming again because of anthropogenic CO2 emissions. Another study you link to says that a long-term cooling trend started 5,000 years ago.

They can't both be correct, can they? Which rather suggests that although use of proxies involves a lot of hard work, and some clever science, the results can't really be trusted that much, at least not when they conflict with the historical record (and with each other).

By the way, your latest link also says "However, Marcott et al. do note in their paper that the ‘uptick’ shown in the graph is not statistically robust...". That uptick is the man-made global warming part of the graph, I believe.

Thanks for the interesting point re NGOs
You say I myself am a little ambivalent on this crisis.etc. I agree and am ambivalent about this as well. I live in NZ. Here our(newly elected) government has offered to take (so called) refugees from Manus Island. These folk have attempted to enter Australia illegally shipped from various parts of Asia by very dubious 'merchants'. Well they (our government) has managed to damage our relationship with the Aussies who are mightily pissed off with our government's virtue signaling.
Illegal and mass migration has to be dealt with - but cannot be allowed to take place at the willy nilly for obvious reasons.
The main reason why our country isn't directly threatened by such migration is that it is so remote. The second is that the Aussie navy intercepts them sharpishly and puts them on Manus island. Be rather tricky for our little navy to deal with!

Re coal : BBC4 just had a repeat of the River Taff 3 parter

re CPC - the one thing that really sticks from reading Mao biographies is his career as a thuggish bandit and warlord.

ST - no problem. I didn't make any attempt to take account of the Earth's curvature. I just calculated the lateral force in newtons and as a fraction of Earth's gravitational force at sea-level. But having thought about it, the Earth's curvature will pose a serious complication for EM's flawed hypothesis as the distance between the masses increases; as the centre of mass of an 2km thick ice sheet will effectively be below the horizontal once the distance is greater than about 100km, thus further weakening the potential for the miniscule lateral force to lift the local sea level.

btw, it is lapogus with an el, as in grouse.

Iapogus. Thanks for doing the recalculation. I was damned if I was going to waste my time. I was merely going to point out that gravity anomalies are measured in milliGalls for a good reason. Finally, EM failed to plot his calculation upon an appropriately curved surface. I suspect both his and your calculations ignore this aspect.

At one time I knew all this stuff. Then when I worked in combination with a geophysicist I left it to him (rarely a her). Then I had to relearn much of it again in order to second mark undergraduate projects. Over the past few years it has slowly sunk again from view (with a few remnant bergy bits remaining to spot the stupid).
